Very very hard – GREAT. Ok PP is correct about the scenes after battling the striders and gunship. For me this opening battle was brilliant. Strategy required but winnable without cheating. No give aways from me mind!
I’ll be playing this again. HL2 FP FPS fanatics like me will love the opening battle.
Level design etc? Er, well, not so good.

If you like difficult combat, play this mod–at least for the beginning battle. For the rest of us, you probably can’t do it without cheating and it might not be worth it.

For some of these mods that I consider impossible, I’d like to see someone record how they did it and upload to youtube. (I believe when Jasper and Phil say it’s possible, I just don’t know how.) I don’t think I’ll ever be good enough to win the strider/gunship battle.
